I had my XChallenge serviced by Rainbow this week and they performed a new GT-1 software update
They said I might like it better
Took it out today and wow, can't believe the difference
The bike seems to have more torque, lower down the rev range and revs freer
Plus there are no vibes and none of the chugging/thumping around town (slower speeds) - it is so smooth............. can't fault it
It is a significant upgrade
